### **Specifications:**  
- **Output Voltage:** 5.0V  
- **Output Current:** 1A (max)  
- **Dropout Voltage:** 0.5V (typ) at 1A  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.3% (typ)  
- **Load Regulation:** 0.4% (typ)  
- **Quiescent Current:** 10mA (typ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  

### **Descriptions:**  
- The LM2940S-5.0 is a fixed 5V low-dropout regulator designed for applications requiring stable power with minimal voltage overhead.  
- It includes built-in protection features such as thermal shutdown and current limiting.  
- Suitable for battery-powered and automotive applications due to its low dropout and robust performance.  

### **Features:**  
- Low dropout voltage (0.5V typical at 1A)  
- Reverse battery protection  
- Internal short-circuit current limiting  
- Thermal shutdown protection  
- High ripple rejection (75dB typ)  
- Adjustable output version available (LM2940)  

This regulator is commonly used in automotive, industrial, and consumer electronics for reliable voltage regulation.
